In addition to advertising gang membership, tattoos provide other details about the bearer. For the incarcerated, images of chains and locks represent the loss of freedom; an hourglass or clock face without hands indicate doing time; a string of numbers may be an inmate's prison ID; one laughing face, one crying face means play now, pay later or my happy life, my sad life; a tombstone with numbers may indicate years of incarceration; the face of a female crying usually means someone on the outside is waiting for them.
